The Hollywood jeweller who designed Angelina's ring, Robert Procop, spoke to American magazine, US Weekly to confirm the rumours, saying that Angie's ring was designed in collaboration with Brad, her partner of seven years.

Procop told US Weekly that Pitt had been "heavily involved" in a design that "perfectly suits Angelina's long slender fingers." Designing and perfecting the rock was reported to have taken around a year.

The couple have six children together, who have reportedly been begging "mummy and daddy" to do the decent thing and get married. Brad and Angelina got together in 2005 on the set of movie Mr and Mrs Smith.
